Question

How can gene flow result in changes in allele frequencies

Answer 1

"Both processes allow for gene flow between populations. Gene flow may changethe frequency and/or the range of alleles in the populations. If populations are large, migration may have little or no effect on allele frequency. However, if populations are small, migration may have a big impact on allele frequency.Oct 22, 2012"-www.slideshare.net/tammi-1990/factors-affecting-allele-frequencies
